I suppose, another application written in .NET4 running on your computer 
and holding the clipboard is crashing due to the Tk clipboard requests.

Clipboard is a shared resource and specially terminal programs 
(UltraVNC, Windows Remote Desktop or any virtualisation software may 
mess this up). Also, I have seen that in Windows 11, there is an 
extension to get an extended cliboard with a history list.

I can reproduce the "usual Clipboard busy errors" with UltraVNC.
It you have "Windows Remote Desktop" active, there is an option when 
setting it up: press Options on the first connection screen, then choose 
"local resources", then Keyboard. Choose "on this computer" there. Also 
uncheck the clipboard checkbox.

Just arbitrary guesses and eventually only noise but anyway,
